+++ This bug was initially created as a clone of Bug #52465 +++ The Veyon proxy app should automatically be install on UCS@school singlemaster systems when updating to 4.4 v9.
The meta package will be upgraded during the upgrade to 4.4 v9. The updated join script will then install a new pre-join hook. But it won't be executed, because the pre-join hook runs before the meta packages join script. Thus the join script now fails if the Veyon app ist not installed and forces the user to rerun it. That will execute the new pre-join hook code and install the Veyon app. QA: I have upload the packages to the test appcenter, so it is installed during the upgrade. We'll see tomorrow what happens in Jenkins… ucs-school-metapackage (12.0.4-4)
QA → All OK → VERIFY (the code was already in 4.4, so reopen is not needed) [4.4] d9d8bf3aa Bug #52525: advisory [4.4] 4dbd7a848 Bug #52525: pre-joinscripts hook installs ucsschool-veyon-proxy app on singleserver Changelog → OK Advisory → OK Jenkins → OK Code → OK 4.4 v9 is existing in test appcenter. SupportedUcsVersions was set to 4.4-6 errata762 (and empty for the veyon-proxy app). I changed both to 4.4-7 errata841 to get the recent changes in the ucs package univention-docker. After that the update & installation work as expected. Note: if the vm has less than 1024 MB RAM, the setup will fail. Using the test appcenter, I updated from 4.4 v8 → v9 in a single server env. In the join.log a visible error was logged, reminding me to rerun the join script again or to install the app manually (which succeeded). The unit tests run during the build & install.
